Anastrepha sinuosa Canal  n. sp.

(Figs 1.C, 2.E & F, 3.G&H)

Type Data. COLOMBIA. Holotype Ƥ, Tolima. Ibagué, El Placer, 4 º 24´53.4 ´´ N 75 º 18´50.8 ´´ W, 1.448 m.a.s.l., 03.XI. 2004, M. R. Castañeda & A. Osorio, McPhail Traps (MEN-UT).

Etymology: The name of this species is an adjective meaning winding (from Latin sinuosum) in reference to the shape of the edge of the aculeus tip.

Recognition: In the key of Korytkowski (2004) A. sinuosa  runs to page 71 to A. lanceola  . The shape of the aculeus of A. sinuosa  is a distinctive character distinguishing it from any other species in the genus because the aculeus is very slender (0,05mm wide) and the aculeus tip is long and sinuous. Tigrero & Salas (2007) described A. tumbalai  which is similar to A. sinuosa  in most aspects, but these species differ by the follow characters: A. tumbalai  ratio aculeus length/oviscape length 0.85 (aculeus shorter than oviscape), aculeus tip length/aculeus length 0.07 and aculeus tip serrate and sharp. In A. sinuosa  the ratio of aculeus/ oviscape length 1 ,0 (i.e. aculeus length equals oviscape length), aculues tip/aculeus length 0.058 and the aculeus tip is not serrate and blunt. The new species resembles A. lanceola Stone  , but the aculeus is thinner in the new species; the aculeus tip in A. lanceola  has lateral protuberances near the end of the oviduct and in the new species there are protuberances at the end of oviduct and at the apex, and the aculeus tip is serrate and sharp in A. lanceola  but not serrate and blunt in A. sinuosa  , the eversible membrane has 20 rather large hooks in A. lanceola  and three rows of different shape teeth in the new species.

Description. Mostly yellow. Setae dark brown; setulae yellowish. Head: 1.07 mm long, 2.07 mm high, 2.0 wide. Yellow except ocellar tubercle black. Face almost flat, in profile concave medially no microtrichose. 4 frontal setae. Antenna 0.53 mm long, 0.15 mm wide in frontal view. Arista pubescent 1.14 mm long. 2 orbital setae well developed. Ocellar setae present but weak, 1.38 times as long as ocellar tubercle. Thorax: Mostly yellow, microtrichose. All scutal vitta absent. Dorsal margin of anepisternum white. Mesonotum 2.40 mm long, 2.03 mm wide. Katepisternal seta long and slender (as long as orbital setae but more slender). Subscutellum and mediotergite entirely yellow. Wing (Fig 1. C): 8.07 mm long, 3.30 mm wide. Cell c 1.2 times as long as pterostigma. Apex of vein R 1 at 0.51 wing length. Apex of vein M strongly curved, finishing near apex of S-band; cell r 4 + 5 0.76 times as wide at apex as at level of DM-Cu. Crossvein R-M at 0.68 length of cell dm. Pattern mostly yellow, most margins of bands, most of pterostigma, basal part of C-band, distal part of S-band and posterior parts of V-band brown. S and C-bands broadly separated. S-band with small cleft in cubital cell. V-band separated from S-band, proximal arm interrupted in cell r 4 + 5. Microtrichose except cells bc, c, bm, parts of bcu and dm, and alula. Abdomen: Tergites yellow. 3.23 mm long. Female terminalia: Oviscape 5.69 mm long, 2.37 times as long as mesonotum. Spiracle at basal 1.30 mm, at 0.23 length of oviscape. Eversible membrane ( Fig 2View FIGURE 2. E, F) with three rows of dorsobasal scales, the posterior row with eight small teeth apically divided in three crests, the middle row with 12 hook-like scales and the anterior row with ten strong spine-like scales, there are five weak hook-like lateral distal scales. Aculeus 5.69 mm long, 0.05 mm wide at midlength, 0.063 mm depth at the end of oviduct, 0.025 mm depth at the middle of the aculeus tip and 0.038 mm depth at the apex. Aculeus tip ( Fig 3View FIGURE 3. G, H) 0.34 mm long, not serrated, blunt and widened at the end of oviduct and at the apex resembling a winding edge.

Comments. Anastrepha sinuosa  resembles species of the mucronota  group
